Patent CA-2325528-C (CA)
Inventor: KAUFHOLD JURGEN
IPC: B29C71/04
Filed: 1999-04-30
Granted: 2006-12-12
Abstract: The invention relates to a process for the production of graded-index profiles in polymeric optical fibres. The process is based on the fact that ionizing radiation causes an increase in the refractive index, for example in PMMA. Therefore, polymeric optical fibres, preforms or fibre-core preforms are irradiated with ionizing radiation of predetermined wavelength and dose while being moved past the radiation source in the longitudinal direction at a given speed and are subsequently tempered for a defined length of time. Through the control of the spatial distribution of the ionizing radiation by means of mirrors, lenses or aperture systems, a uniform radial graded-index profile is produced over the entire fibre length, with the result that the polymeric fibre, used as an optical waveguide, has considerably improved transmission characteristics for optical signals.

Abstract: The invention relates to implementation of multiple simultaneous calls for a mobile station in a mobile communication system. A  common traffic channel (TCH) is allocated to several simultaneous calls (applications 1-n) of the mobile station (MS), so that the calls share the capacity of the common channel. Logical links are established for each call inside a common radio link protocol or link access control protocol, which is established over the common traffic channel between the mobile station (MS) and an interworking function (IWF).  The common traffic channel (TCH) is allocated when the first call or calls are set up, and the capacity of the traffic channel is adjusted dynamically during the calls. The capacity of the common traffic channel is increased or the allocatd capacity is reallocated when a new call is added to the traffic channel. Correspondingly, the capacity is decreased or the allocated capacity is reallocated when a call is cleared from the common traffic channel. The common traffic channel is released after the last call has been cleared.

Title: Apparatus for dispensing a porous carrier
Inventor: WILLEMSEN LOUIS RINZE HENRICUS
IPC: B65D83/04
Filed: 1999-07-05
Granted: 2008-09-23
Abstract: The invention relates to an apparatus for dispensing or releasing a porous carrier (12), wherein the apparatus comprises: a supply chamber (1) for the porous carrier (12); and ejection means (9) for causing the carrier (12) to move gradually outside the supply chamber. According to another preferred embodiment the ejection means (9) comprise an outlet opening (2) which is arranged in the end wall of the supply chamber (1) and the dimension of which is such that the porous carrier (12) moves through the outlet opening (2) only when the ejecting body (9) is operated. Thus is achieved that the carrier (12) is not accidentally moved outward to an excessive degree. According to a particularly important embodiment the porous carrier (12) is divided into separate elements in lengthwise direction and the elements move through the outlet opening one by one when the ejecting body (9) is operated. This enables use of separate elements (12) in the form of the cotton wool pads typical in this field.
Patent CA-2339715-C (CA)

Granted: 2008-04-29
Abstract: The invention provides for an improved method of removing debris from a producing oil, gas, or commercial water well without the necessity of using a service rig or retraction of the tubing string. In accordance with this method there is provided a side entry sub that is situated in the well casing string. The side entry sub has an access port with a hollow feed passageway permitting the introduction of coiled tubing into the main flow passage. The coiled tubing is passed down the main flow passage adjacent to the tubing string to the desired depth. Fluids are then introduced into the well through the coiled tubing. The fluids mix with the debris and the mixture is forced to flow out of the well using the tubing string or the main flow passage of the production casing. This flow of liquefied debris facilitates effective extraction of the debris from the well without the need of a servicing rig for production tubing retraction and intervention with specialized cleanout tools.

Abstract: Detonating projectiles are fired into a target area by a weapon, the time between firing and detonation being one second or less. By setting the target location at the same distance as e.g. the edge (1) of a building (3), however laterally displaced with respect to that edge, it is possible to obtain an effect also in an area invisible to the bearer of the weapon. For simulating this weapon, for example in house-to-house fighting, it is proposed to affix devices (5) comprising a sensor (22) and a transmitter (27) to obstacles. When the weapon is fired, a simulation device provided on the weapon transmits a firing signal to the sensor (22), the latter activating the transmitter (27). Similarly to the real effect of the weapon, the transmitter (27) emits an impact signal in the impact area (7) which also includes the mentioned area which is invisible to the bearer of the weapon. On account of the independent operation of the transceiver unit (5), it is possible to simulate the effect of this weapon substantially without delay as compared to reality.

Abstract: Using a solution mining procedure, an ore (10) is treated with a solution of acetic acid and hydrogen peroxide so as to form a leachate containing lead ions.  Lead ions (and other metal ions such as zinc and manganese) are stripped (22, 24, 26) by solvent extraction from the leachate to form separate aqueous solutions. The aqueous solution containing lead ions is treated electrochemically in the anodic compartment of a separated electrochemical cell (42) to form a precipitate of lead oxide. Manganese dioxide can be produced similarly (72). A precipitate of zinc hydroxide can be formed in the cathode compartment of a separated electrochemical cell (56). In the cells (42, 72) extracting lead ions and manganese ions, the cathode compartment is used to generate hydrogen peroxide (for use in making the leachant), either directly or indirectly.

Title: Electrophoretic, high index, or phase transition control of total internal reflection in high efficiency variable reflectivity image displays
Inventor: KOTLICKI ANDRZEJ
IPC: G02F1/1677
Filed: 2000-05-26
Granted: 2005-07-05
Abstract: Charged particles (21) suspended in a medium (20) such as Fluorinert.TM. Electronic Liquid are used to electrophoretically control total internal reflection (TIR) at a retro-reflective surface formed on a high refractive index material. Prismatic structures (35, 32, 81) redirect ambient light from an overhead light source toward a display image and then from the image to the region in front of the image, yielding a high contrast reflective display. A transparent planar waveguide (36) front lights the display with sequential flashes of red, blue and green light to generate a full colour display. TIR can also be controlled at retro-reflective surfaces by means of a vapour-liquid phase transition, or by changing the absorption coefficient of a material using electrical, chemical and/or electrochemical methods.

Abstract: The present invention is directed to providing systems and methods for remotely monitoring sites to provide real time information which can readily permit false alarms to be distinguished, and which can identify and track the precise location of an alarm. In exemplary embodiments, monitoring capabilities such as intrusion/fire detection and tracking capabilities, can be implemented through the use of multistate indicators in a novel interface which permits information to be transmitted using standard network protocols (IP) from a remote site to a monitoring station in real-ti me over preexisting communication networks, such as the Internet (304). A wireless network (302) can also be established using brows er encapsulated communication programs to transmit data packets which comply with any standard wireless local area network protocol (306). Communications can thereby be established between a web server (420) embedded in a centrally located host monitoring station (202) and a separate security panel (206).
